A unifying principle that explains a body of facts and/or those laws that are based on them.

The study of matter and the changes it undergoes.

A form of matter that has a definite composition and distinct properties.

A combination of two or more substances in which the substances retain their distinct identities.

The composition of the mixture is the same throughout (at the atomic/molecular level).

The composition is not uniform throughout.

Can be used to separate a mixture into its pure components.

A substance that cannot be separated into simpler substances by chemical means.

a substance composed of atoms of two or more elements chemically united in fixed proportions.

Degree of agreement among several measurements of the same quantity.

A statement based on direct experience

A statement that is proposed, without actual proof, to explain a set of facts or their relationship

The formulation of an apparent relationship among certain observed phenomena, which has been verified to some extent.

If experiments contradict the theory, the theory may have to be modified or discarded

Deals with the study of carbon and the chemicals in living organisms

Is the study of life or of chemical processes in living organisms.
